...certain validations realtime. The data resides in the controllers attached to the machines and that data from the different machines should be transmitted thru ethernet or RS 232 to the database of our server without any timelag and with timestamp on them. The data should be grabbed nearly every second. The controllers from which we propose to grab data

Sending data out through com2 modbus : If modbus mode is set, send out data through comport in modbus protocol. Modbus over RS485, with an external 232 to 485 driver. (Later we will add modbus TCP). Pls quote for this separately.
Setting system statuses and supporting debug : 4 or 5 digital outputs to be used to set the statuses

Hello,
I want arduino device which will can communicate with modbus 232 and 485 protocols.
The device should be connected to internet via GSM module and should send data to MQTT server in every 5-10 secs.
The device should also cache the data if there is no internet connectivity and should send the cached data to internet via GSM whenever there will

We need some python software so to run as a service on on a linux box collecting data from an rfid antenna over seriel rs 232 and the commands are sendt and recived as hex
The reading should be able to be configured as timed activation and as trigger
The data has to be stored in a database sql maria ...
Command examples
Please check below hex commands

We want to design LCD Panel based configuration module that will use RS 232 to give command to the main board. Our board has RS 232 port for configuring device but we want to use LCD panel to configure the same.
can share more details if someone there can let us know there skill sets.

A freelancer has to build a program based on PIC, that automatically manages the data flow direction of the RS-485 serial port from RS-232, taking into account the baud rate and the number of bits, without any special configuration or software command, i.e, totally transparent to the MCU.
It must be 100% compatible with Modbus!
Freelancer has to deliver:

...extra high-speed RS-232/422/485 ports.
It must have the auto-tune baud rate and data format to the RS-485 network (totally compatible with Modbus).
The power converter derives from the USB port and doesn’t need any power adapter.
It also features a high-speed 921 Kb/s transmission rate support to various O.S. independent RS-232/422/485 Ports.
I will

...from through their RS-232 interfaces.
The program will need to be able to identify local ports (on PC or PI), choose communications settings and open ports for communications. We need to be able to send commands (in ASCII) and receive responses through buffers that we can further process or store.
We'd like to have a common code base (PC and PI) that

Design an Industrial RS-232 to RS-422/485 Converter from the scratch.
Isolation in RS-422/485 side and Isolation in Power input side.
Power Input 9- 36 VDC and VAC.
Milestones:
1) Receive the concept and specifications
2) After approved with the right components, design the schematics.
3) Analyze the enclosure for the PCB layout dimensions and design

Design 3 products as I will provide the enclosure and the freelancer must provide the PCB complete de...communicating in a TCP Modbus Network
2) It will have 4 analog input and 1 analog output as well as a watchdog timer circuit communicating in a TCP Modbus Network
3) It's a RS-232/422/485 LoraWan Converter to communicate with those products above.

I have a project with 2 micro controllers communicating over RS-232 and I have the need for a robust communications and command processing protocol on one of the microcontrollers (the slave device).
Commands are received between start and end markers < and > to ensure the full message is received before processing. eg: <command>

...this will help explain this protocol and communication standard.
1. In the old days.....nearly all of the lab equipment communicated on some form of serial port, either RS-232 or even RS-422. As such, the first priority of the DCS was to keep the packets small for speed of transmission. Hence the situation where the DCS maybe has 200 possible data
